The book is based on the premise that it is difficult, if not impossible, to manage a modern business or public organisation without at least some knowledge of information technology. Managers need to have an understanding of strategic development, including the current technology situation, the current and desired business situation, the need for changes, the application portfolio, and organisational and human resources issues in the area of information technology. The book covers important management aspects of information technology. In addition, it provides insights into management research, both on how it is conducted and what results are obtained.
